Wad for whale guns and the like



March 25, 1930.v K. E. H. ENGBERG WAD FOR WHALE GUNS AND THE LIKE Filed Aug. 2l. 1928 Patented Mar. 25, 1939 KARL EMIL HJ'ALMAR ENGBERG, 0F DRAIIIIVIEN, NORWAY WAD' FOR W'HALE GUNS AND THE IKE Application led August 21, i928, Serial No. 301,080, and `in Sweden `'l'uly 24, 1928.

In guns for the shooting of harpoons and the like it is an essential condition that an effective tightening or packing is provided between the propellant charge and the inner end of the harpoon, and to this eliect is used a Wad, which hitherto has consisted of two resilient tightening discs between which is loosely placed a resilient filler.

The insertion of such wads in position is a task which demands considerable time, and moreover it is impossible to insert the same in such manner that always similar or uniform shot eliects are obtainable, the load and other conditions being the same.

In muzzle loaded guns the bag of powder has hitherto been inserted by means of a ramrod whereupon the first tightening disc is inserted and firmly pressed against the powder bag. Then resilient filler, so-called shooting wool is successively inserted in the desired amount and rammed against the first disc, and at last the second or foremost tightening disc is inserted and pressed H against said shooting wool. 2D If breechloading guns are used the cartridge has after the insertion of the powder to be provided with a wad in a similar Way, whereupon the edge of the cartridge is bent inwardly to secure the wad in position.

However, this operation only can be reiterated a few times when the said edge is destroyed, and accordingly the life of the cartridge will be very short.

The said drawbacks are avoided by the present invention, whereby a more rapid succession of shots is possible, which is ot very great importance in the capture of whales and similar sea animals. At the same time great uniformity of the shots is secured.

The annexed drawings illustrate and eX- plain my invention.

Fig. 1 shows in longitudinal axial section an embodiment of the invention, and

Fig. 2 is a view taken against the right hand end of Fig. 1.

In the drawing 7 represents the casing or housing which is formed of any suitable material such as paper carton or the like. The housing which may have any suitable diameter and length is closed at one (the foremost) end.

In this housing is first inserted a disc 8 of resilient material such as rubber. Then is inserted a resilient liller 9, consisting preferably of so-called shooting wool, in a suitable amount and at least another tightening disc 10 formed of the same resilient material as the disc 8. The disc l0 is pressed against the liller 9 until the latter is suitably com- 6.0 pressed, whereupon the disc 10 is secured in the housing 7. This may be obtained by means et any suitable means such as a spider or a star shaped metal disc 11, the points 1l of which are bent somewhat backwardly when the disc is inserted in the said housing 7. then the compression of the ller 6 seeks to press the disc 1l backwardly the points l1 will penetrate a little into the wall of the housing 7 and thus be secured in po- 70 sition. The housing 7 is made so much longer than the wad proper that a chamber 12 is obtained at the rear end thereof which chamber may receive the powder bag.

Instead of the said chamber the wad may be provided with other suitable means for taking up the powder bag.

Due to the fact that my wad consists of one integral body the same may together with the powder bag be inserted in the gun barrel or the cartridge with no loss of time which often is very important. Moreover the wads will be uniform both as regards dimensions and elasticity whereby uniform effects are obtained in tiring.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:

1. A wad for guns for shooting out harpoons consisting of two tightening discs and an intermediate resilient filler, a housing surrounding said discs and ller, and means at one end of said housing for containing the 9 powder bag.

2. A wad for guns for shooting out harpoons consisting of two tightening discs and an intermediate resilient filler, a housing surrounding said discs and filler, said housing ico at one end having a chamber for the reception of the powder bag.

3. A wad yfor guns for shooting out harpoons consisting of two resilient tightening discs and an intermediate resilient material combined as a unit, a housing for receiving said unit and locking means for preventing longitudinal displacement of the rear tightening disc when in position. n

4f. A wad forguns for shooting out harpoons consisting of two tightening discsl and an intermediateresilient material combined as a unit, a housing for receiving said unit, locking means for preventing; longitudinal displacement of the rear tightening disc when in position, and means consisting of a vstar shaped disc the diameter of which isl greater than ythat of the bore of the housing.

Y In testimony whereof I affix my'signature.V
